I wanted mod_perl on my gentoo system. It seems to be touchy about thread safety. Well that seemed reasonable, but it failed to emerge (gentoo-speak for "install from source"), and left me without my favorite editor (!!!): vim. To handle thread-safety issues, I put this in /etc/package.use: > # perl needs threads for mod_perl to work (or else mod_perl can't have threads) > # Moreover vim cannot be built unless perl and libperl have the same use flags > dev-lang/perl ithreads -ldap perlsuid doc > sys-devel/libperl ithreads -ldap perlsuid doc > www-apache/mod_perl ithreads -ldap doc The result was failure. I was not rebuilding vim, but it got killed in the process anyway: it errors out on startup. Moreover, I cannot re-emerge vim either, because it fails in about the same way as mod_perl. Both perl and libperl seem to build okay with the above lines in package-use. My running kernel matches /usr/src/linux, so the headers should be good. I'm looking for guidance from anyone who's using mod_perl with apache. Here's the build log: treat portage # cat /var/tmp/portage/www-apache/mod_perl-2.0.4-r1/temp/build.log >>> Unpacking source... >>> Unpacking mod_perl-2.0.4.tar.gz to /var/tmp/portage/www-apache/mod_perl-2.0.4-r1/work * Applying mod_perl-2.0.1-sneak-tmpdir.patch ...
